HCl, cooled in ice, and diazotized with sodium nitrite solution, until starch iodide paper showed excess nitrous acid.
In this process the amine salt is dissolved in absolute alcohol and diazotized by the addition of amyl nitrite; a crystalline precipitate of the diazonium salt is formed on standing, or on the addition of a small quantity of ether.

Among such dyestuffs are chrysamine or flavophenine, obtained from salicylic acid and diazotized benzidine, and congo red obtained from sodium naphthionate and diazotized benzidine.
By itself diazotized primuline is slowly influenced by light, but quickly acted on in presence of organic substances.
As said above, primuline is transformed by nitrous oxide into a diazotized compound, and consequently the material is now susceptible of being acted on by light.
In other words, the diazotized primuline acts as a mordant only when not altered by the luminous action.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "diazotized" in a variety of sentences. We hope that you will now be able to make sentences using this word.
